HORSE-POWER.

SPECIFECATON forming part of Letters Patent No. 353,967, dated December 7, 1886.

Application filed November 14, 1885.

.To all whom it may concern.-

Be it known that we, GEORGE RAYMOND and ALBERT RAYMOND, citizens of the United States, residing in Chicago, county of Cook, and State of Illinois, haveinventcd certain new and useful Improvements in Horse-Powers, of which the following is a specitication.

In horse-powers of this character it is necessary, in order to get sufficient leverage, to apply the power to wheels of large diameter, and in using such wheels it is necessary either to use double or triple gearing from them, in order to balance the strain on opposite parts of the wheel, or to make the entire wheel of such weight and strength as to enable it to transmit the entire force applied to it from a single point without giving way. The great weight which must be given to large wheels to be used in the latter way is a source of expense and inconvenience, and their use is attended with frequent accidents.y Double or triple geared wheels have therefore come to be more generally used; but with these the difficulty has been found that thecutting of the cogs is almost always somewhat irregular, so that if the wheel is mounted to maintain at all times precisely the same position the entire strain is liable at any time-to wit, when wheel to bear upon one only of the driven pinions-to be thrown upon the wheel at a singlepoint-a situation which is likely to result in the breaking ofthe wheel.

Our invention consists,chiedy,in providing a simple and inexpensive means for allowing the gear-wheels to automatically adjust themselves to each other when any inequality in the cutting of the cogs presents itself, so that the strain can never be thrown upon a single part of the large wheel; and to this end we propose to furnish the large or master wheel with two points only, upon which it can bear' horizontally, these points consisting of two rotating collars placed within the rim of the master-wheel and at opposite ends of adiameter, the master-wheel being thus fixed without possibility of lateral movement in one direction, but having a play allowed it within certain limits in the direction perpendicular thereto. This play permits the requisite au tomatic adjustment of the wheel to its driven Serial No. 182,847. (No model.)n

pinions, which are placed within the wheel, or without it, if desired, at ornear the bearingcollars.

Our invention further consists in certain details of construction, hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, which form a part of this specification, Figure 1 is an elevation of our improved horse-power, the same being shown geared to a grinding-mill. Fig. 2 is a plan view of the same, the standard and upper part being removed. Fig. 3 is a crosssection on line 3 3 of Fig. 2. Fig. 4 is acrosssection of the whole structure on line 4 4 of Fig. 2. Fig. 5 is a detail ot' the' means by which the hopper is attached to the shaft, and Fig. 6 represents a means of bracing the upright portion of the mill.

The horse-power is mounted upon a framework formed of longitudinal timbers l 1, united by cross-timbers 2 3 4 5. A quadrilateral cast-iron framing, 6, with arms extending inward to a center or core, 7, is bolted to this frame, and has tixed within it five short shafts, 8, 9, 10, 11, and 12. Upon each of the shafts 8 and 10 are fixed, respectively, cogged wheels 13 14, to which are made fast pinions 15 and 16. upon these pinions, and are held down by pins Flanged collars 17 and 18 ride 19 and 20, passing through the said shafts 8 and 10. Upon the shafts 9 and 11 are two similar double-flanged collars, 21 and 22, free to revolve upon the shafts, but restrained from vertical movement by a pin above and a shoulder below each collar.

The master-wheel 23, cogged upon its inner surface and having an inwardly-projecting flange, 24, rests upon the upper 'surfaces of the two pinions 15 and 16, and is kept from vertical displacement by the Iianges of the collars 17, 18, 21, and 22. Sweeps 25 and 26 are attached, as shown in Fig. 2, to the masterwheel, and the motion of the mastenwheel is communicated, by means ofthe cogs on its inner face, to the pinions 15 and 16, and thence through the wheels 13 and 14 to the pinion 27, arbored upon shaft 12. The pinion 27 has an upwardly-projecting extension or sleeve, 28, upon which is secured a gear-wheel, 29, meshing with a pinion, 30, which is in one piece with a cylinder, 3l, revolving about the main IOO i the grain.

shaft 32 of the mill, and resting upon awasher, 33. A second horizontal shaft, 34, is arbored in the cross-timbers 4 andf5, its extremity be ing supported by a casting, 35, bolted to the primary frame-work 6. Upon the inner end of this shaft is Xed a beveledY pinion, 36, gearing with a second bevel-gear formed upon pinion 27. This shaft and gearing permit the mill to be driven by power applied from a steam-engine or other motor independent of the sweep, and it also enables any surplus power toghe taken off from the machine for the purpose of operating a second mill or other mechanism by means of the power of the sweep.

It will be observed that a collar, 37, is fixed upon the shaft 12 above the sleeve 28, in order to prevent upward motion of the pinion 27 and sleeve 28 under the upward pressure of pinion 36.

It will be observed that the masterwheel 23 has a slight horizontal play outside the collars 21 22, and that it has no play outside of the collars 17 18. It will result from this, as above explained, that in case of anyinequality in the cutting ofthe cogs on the master-wheel, or the pinions 15 and 16, the master-wheel will be permitted to shift its position, so as t0 maintain an equal strain upon the cogs ofthe two pinions 15 and 16, and it will be impossible for the entire strain to be thrown upon the cogson one side only of the master-wheel.

It will also be observed that the friction between the master-wheel andthe pinions 1516, upon which it rests, tends to revolve those pinions in their normal direction of motion, and therefore the power used to overcome this friction is not, as has heretofore been the case, lost power.

Referring now to Fig. 4, a second cylinder, 38, surrounding the main shaft, rests upon the cylinder 3l, and is attached to it by means of wooden pins 39,passing through flanges formed on the engaging ends of the two cylinders, respectively. The cylinder 38 carries at its upper end, upon a circumferential iiange, 40, the revolving millstone 41, which receives its motion through the supporting-cylinders 31 and 38. rlhe upper millstone, 42, is bolted to a casting, 43, itted with a spline upon the upper end of the shaft, and carrying a hooked arm, 44, for the bag or other receptacle for A nut, 46, on the screwvthreaded upper end of the shaft, is provided for regulating the distance between the stones when .grinding, this nut serving to determine the vertical locationof casing 43. A piece of rubber, 62, supported bya pin passing through the shaft, serves to hold the stones apart when there is no grain between them. The hopper 45 is dovetailed upon the ripper part of the casing 43, as shown in cross-section in Fig. 5. An angle-piece, 61, is bolted to the hopper and passes freely over theupper end of the shaft, bracing the hopper. n

Bolted to the block 48, hinged to the bottom ofthe hopper, is the shake-pan 49. An arm,

50, also bolted to the block 48, extends down around the casing 43, and has screwed to it a shoe, 51, which bears upon the cylinder 38,

screw, 55, passing through a slot in the said A slide, regulates the size of the aperture at the bottom ofthe hopper, according toits location, it being adjustable through the play afforded by the slot upon the bolt of the thumblscrew. The wooden pins 39 afford the usual guard for the millstones against injury from foreign sub-V stances coming accidentally between them, breaking in case of such accident, and permitting the cylinder 38 and running-stone to stop.

In order to insure firmness and rigidity of the upright shaft and cylinder,we have devised thebracingarrangementshowninFig.6.. When this is used three of the shafts, 8, 9, 10, and 11, are caused to project through the top piece or cover, 56, which protects the lower part of the mechanism, and nuts 57 are screw-threaded upon them, said nuts having attached thereto three brace-rods, one of them being only shown in dotted lines in Fig. 6, attached to a collar, 60, surrounding the shaft 38, and holding it rigidly and firmly in position.

The particular location of the main shaft which we have shown is not essential to our construction. It may, if desired, be placed in the center as a continuation of the-short shaft` 12. The arrangement shown is a convenient means of attaining a high rate 'of speed to the running-stone.

IOO

We wish it understood that we .do not limit l ourselves to the particular arrangement of master-wheel and pinions shown, since our invention consists, broadly, in so mounting a master-wheel that it shall have a play to adjust itself as required by inequalities in the cutting of the cogs and continuously main? tained its multiple bearing.
